    ### Get output header and WCS
    if wcs is None:
        header, output_wcs = utils.make_wcsheader(ra=ra, dec=dec, size=size, pixscale=pixscale, get_hdu=False)
    else:
        output_wcs = wcs.copy()
        if not hasattr(output_wcs, 'pscale'):
            output_wcs.pscale = utils.get_wcs_pscale(output_wcs)
            
        header = utils.to_header(output_wcs, relax=True)
